Migration from AMD 690G to 780G (2 Viewers)

I get nice HD pictures with CoreAVC too. Just a shame that I can't with PowerDVD etc. 'cos then I would be using the ATI card rather than the CPU to do the leg work.
Check your CPU usage when doing HD vs SD. Then try an HD with PowerDVD (Ultra) and see the difference.
Can't remember if HD looks better when using PowerDVD, but switching channels eventually causes problems - problems that many have experienced with both integrated and non-integrated HD ATI cards.
Worst case scenario is I buy an 8500GT (or better) and turn off the ATI card.
I've tried all the Catalyst drivers (from Gigabyte and AMD) with no luck. MP works; I just have to drive the video decoding through the CPU with CoreAVC.

I've now switched off hardware decode from cyberlink powerDVD7 even for SD content.
The onboard ATI card keeps crashing when hardware decode is enabled.
I would rather have it work and use a bit more power than have it not work but with a cooler CPU.
Hopefully ATI will fix this soon ????? - or maybe they will just release a new chipset and not bother - we've all seen that happen before.
I watched TV for the whole evening last night without a single crash! I have never managed that with hardware decode enabled.
The other problem with hardware decode (it seems to me) is that the onboard graphics chipset gets really hot when it is not doing much. (my NB heatsink is probably at 60-70C given I can keep my finger on it for no more than 10secs.) It will get stinking hot when tasked with hardware decode. Maybe this is another reason for instability ... it needs better cooling.
Why is it that so much hardware gets fantastic reviews even when it doesn't actually work properly?

Ok, here I am again: I made the migration, using the Gigabyte board, since my dealer had this one on stock.
First, I simply replaced the board and started the computer. Windows came up, detected a lot of new hardware, installed even more drivers and left me with a fully working MediaPortal! Wow - I didn't expect this!
(probably I will still make a fresh install, but windows' device manager doesnt show any problems or devices with exclamation marks so far).
Second, CPU load now is down to 10% when watching H.264 HDTV (AnixeHD, Luxe HD). Thats what I was aiming for - very nice.
But, STABILITY is an issue! I had several crashes with cyberlinks PDVD7 decoder (DXVA enabled). The reason for this being unclear, but I suppose it is not a heat problem (the chipset gets damn hot though), since I can watch a single HDTV channel over hours with no probs. The good news in this is, that the there is hope that a future driver (or board bios) may cure the desease. I didn't observe the board's behaviour with DXVA disabled yet, but from the posts in this forum (and others) the problem lies somewhere in DXVA.
As soon as I have more information I will come back.

Hi all,
I can also confirm this - I also use 780 Chipset on Gigabyte Mobo - and have crashes/freezes when enabling HW acceleration - work's fine w/o HWacc., but I bought the board just for using the 780's hw features - grrr... I don't know, if it's BIOS/HW/driver related, but highly interested if anyone finds a solution for stable operations with HWacc.

I also have GigaByte GA-MA78GM-S2H met AMD Athlon 64 X2 4850E 45W.
With XP2005 and catalyst driver 8.5, but my floppyDVBs have broken down, have been repaired and are somewhere between Austria and the Netherlands.
What catalyst driver you guys using? 8.5? Tried other ones?
Vista / XP / XP MCE?
Clean install?
FloppyDVB
DVB-C / T/ S/ S?
Ect..
Tried catalyst 8.6 beta drivers?
ATI Catalyst 8.6 Windows XP Beta (32|64) download from Guru3D.com
ATI Catalyst 8.6 Windows Vista Beta (32|64) download from Guru3D.com

Well, I have a Nova-T 500HD and have tried all but the beta 8.6 drivers.
Having a few problems at the moment after a BIOS upgrade to F4. Sometimes MP is not starting properly and it's useless after standby. Am trying a few Power Scheduler options, but am really running out of patience,
Did Gigabyte/AMD overpromise/sell defective goods? Not sure. It runs HD stuff quite well (which is what all the reviewers would have done), until you switch from, say 720p to 1080i and back again a few times. I will never buy a first revision motherboard again.

@huckster2
Are you running XP or Vista?
Perhaps only an XP problem?
Hi pnyberg,
You also have this motherboard and no issues?
What is your exact config bios / catalyst ect?
